MICHAEL POWER, OF TORONTO, ONTARIO, CANADA, ASSIGNOR OF TWENTY-FIVE ONE- A HUNDREDTHS TO ROBERT HEIBER BOWES AND TWENTY-FOUR ONE-HUNDREDTHS TO ROBERT GEORGE DICKSON, BOTH, OF TORONTO, CANADA.

' WINDOW-VENTILATOR.

Application filedOctober 25, 1910. Serial No. 589,024.

To aZZ w/wm it may concern:

Be it known that I, MICHAEL POWER, a

subject of the King-of Great Britain, and resident of the city of Toronto, county of York, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in 'Window-Ventilators; and I do hereby declare that the following is a full, clear, and exact description of the same.

The invention relates-to improvements in window ventilators, as described in the following specificat-ion and illustrated in the apcompanying drawings that form part of novel construction and arrangement of parts, whereby the outside air entering through the window 'is directed upwardly by a pivotal member hinged at the bottom to an open frame adapted to be placed in the window frame.

The objects of the invention are, to facilitate the proper ventilation of a room without creating an objectionable draft, and

to devise a simple form of ventilator which may be placed in any window frame and maybe readily adapted to either te1nporary or permanent uses.

In the drawings, Figure view, partly broken away, of the lower portion of a window frame showing my device placed therein beneath the ordinary window sash. Fig. 2 is an enlarged vertical cross sectional view of my device, partly broken is avertical cross sectional View of a portion of the device showing a slightly modified nlean s for closing the opening 'a't the pivotal joi ntT "Fig. kisg n enlarged horizontal sectional view of one end of the ventilator frame and a port-ion of the indow frame- Fig. dis a perspective detail of a portion of a ventilator sash showing aslight modification of the means for closing the openings at the ends of the pivotal sash.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, T'is a Wlndow frame having the stops 2 and parting strips 3 in the sides thereof and a sash 4 operating therebetween.

Specification of Letters Patent.

1 is a perspective Patented Apr. 9, 1912.

5 is an open'frame having the vertical re rails, and the top rail 7 projecting inwardly.

' 8 is a. rib projecting upwardlyfrom the beveled top edge of the bottom rail 9 arranged. at the inner edge and extending from end to end thereof, said rib having an arc-shaped upper surface in cross-section.

10 is a glazed sash pivotally secured at .the outer side of its bottom rail to the inner side of the'bottom' rail 9 of the frame 5 by the hinges 11 t and adapted to fit snugly against the inner face of the frame 5 and to swing inwardly therefrom.- 'The sash 10 is preferably recessed atthe inner side to receive the glass lights and these are secured in place by the strips 12 in the usual vmanner. 13 is a shield, preferably formed of a strip of sheet metal formed substantially arc-shaped in cross section and secured to the outer face of the sash 10' and extending over the rib 8 carries the water dripping from the glass over the said rib 8, whether the sash 10 is open or closed, consequently it willnot leak through to the inside of the window. This construction also prevents the ingress ofair to the room through the opening at the hinge joint between the sash and frame. l I

14 are pieces of cloth, leather, or other flexible material of bellows formfsecured to the end edges of the sash 10 and to the inner recessed sides of the frame 5 andare adapted to fold inwardly into'saidrecesses on the closing of the sash. The flexible bel lows members prevent s the flow of air around the ends of the sash and the said.

sash when open, directs the flow of air up wardly thus thoroughly ventilating the room without creating a draft.

tudinally thereof adapted to receive the perpendicular edge of the frame 5, said strip being loosely secured to the frame by the screws-19 secured therein and extending into the orifices 20 in the end rails of said frame.

21 are flatbowed springs secured to the inner wall of the vertical slot in the strip 18 and engaging the edge of the frame 5 to hold said strip outwardly.

In placing this device in a window frame, the strip 18 is inserted between the stops 2 and the parting strips 3 and the frame 5 is pushed into the slot in the strip 18 until the opposite end of the frame will slip between the stop and parting strip at the other side of the window frame. When the frame is released the springs 21 move it outwardly between said stop and parting strip. The frame 5is thus securely held in place in the window frame, no apertures being left for the entrance of flies or other insects.

The device may be utilized in the manner described under the ordinary sash in a window in dwellings,railway car-s, or in fact anywhere desired, or the window sash itself may be made to receive the pivotal sash 10, said pivotal sash directing the air upwardly and preventing a draft blowing on aperson sitting close to the window. When the frame is thus placed in position itmay be locked securely against removal by any suitable means. A pin 22 attached to a shortchain 23 is shown inserted into a hole 2-4 in the strip 18, said pin extending into a corresponding hole in the sash.

In Fig. 5, I show a slight modification of the means for closing the openings at the ends of the pivotal sash, in this figure, I show a pair of triangular shaped metal plates 25 hingediogether and to the inner edge of the end of the pivotal sash and to the frame 5 so that they will fold inwardly on the upward swinging of the said sash. The opening in the frame 5 is preferably covered over by a suit-able screen 26 to prevent insects entering the room or when the device is used in railway cars the screen may against the shield secured to the swinging .sash. A very secure and weather proof joint is thus secured.

\Vhat I claim as my invention is 1. In a window ventilator, a frame hav ing an opening therethrough, a sash hinged at its lower edge to the-bottom rail of said frame, means for closing the openings at the ends of said sash when it is swung inwardly, a member extending longitudinally from end to end of the top side of the lower rail of said frame and projecting upwardly therefrom, and-an are shaped shield member secured to the outer side of the lower rail of said sash and projecting over said longitudinal member.

2. In a window ventilator, a frame hav- .ing an opening therethrough, a sash hinged at its lower edge to the bottom rail of said frame, means for closing the openings at the ends of said sash when it is swung inwardly, a metal strip rigidly secured to the upper edge of the lower rail of said frame extending from end to end thereof and having an upwardly and.inwardly extending portion are shaped in cross section, and a metal strip rigidly secured to the outer face of the lower rail of said sash and extending from end to end thereof and having an outwardly and downwardly projecting portion are shaped in cross section fitting snugly .against the are shaped portion of the strip on said frame.

Signed at the city of Toronto, county of York, Province of Ontario, in the'Dominion of Canada, this 21st day of October 1910.

MICHAEL POWER.

In the presence of- H. 'DENNISON, E. HERON.
